Abstract (en)
[origin: EP2261581A1] An air-conditioning apparatus (1) is provided with a two-stage-compression-type compression mechanism (2), a heat source-side heat exchanger (4), a usage-side heat exchanger (6), an intercooler (7), an intercooler bypass tube (9), and an intake return tube (92). The intercooler (7) is provided to an intermediate refrigerant tube (8) for drawing refrigerant discharged from the first-stage compression element (2c) into the second-stage compression element (2d), and the intercooler functions as a cooler of the refrigerant discharged from the first-stage compression element (2c) and drawn into the second-stage compression element (2d). The intercooler bypass tube (9) is connected to the intermediate refrigerant tube (8) so as to bypass the intercooler (7). The intake return tube (92) is a refrigerant tube for connecting the intercooler (7) and the intake side of the compression mechanism (2).
